Using the pre-commit mypy plugin throws internal library errors

Using the pre-commit implementation of mypy throws an INTERNAL ERROR on a project that was previously working. Note that running the same version of mypy from the command line against the same files (in a devcontainer) works as expected.

Pre-commit project can be found at: https://github.com/pre-commit/pre-commit Version 4.3.0

From the pre-commit configuration: running mypy v1.18.2

To Reproduce

Create python project, configure git and install the pre-commit hook

Expected Behavior

Expected to run mypy testing on changed files as usual.

Actual Behavior

vscode ➜ /workspace/internalapi (internalapi_apm_and_logs) $ pre-commit run mypy
mypy.....................................................................Failed
- hook id: mypy
- exit code: 2

Your Environment

• Mypy version used: 1.18.2
• Mypy command-line flags: --show-traceback, --check-untyped-defs, --ignore-missing-imports, --config-file=pyproject.toml
• Mypy configuration options from mypy.ini (and other config files):
• Python version used: 3.12

Reproduziere den Fehler mit pre-commit run mypy unter Verwendung von Python 3.12, mypy 1.18.2 und den aufgeführten Flags und vergleiche ihn anschließend mit dem Aufruf über die Befehlszeile. Beginne beim Traceback des semantischen Analysators in mypy/semanal.py und bei der Annotation in django-stubs/http/request.pyi:56. Die Aufgabe ist erledigt, wenn der pre-commit-Hook bei der Prüfung derselben Dateien ohne den INTERNAL ERROR abgeschlossen wird.
